"I really liked this recipe and took it to the school for hot lunch. The kids really enjoyed it. Use all the regular toppings: sour cream, cheddar cheese, olives, etc."
"Made this tonight for my family and they LOVED it. I cut the calories by using 90/10 ground beef and reduced fat cheese. Used the Healthy spaghetti. Spiced it up with hot and spicy Taco mix. Left out olives and mushrooms since my family doesn't like either."
"I made some changes to the recipe. Not particularly liking black olives, I increased the amount of mushrooms to approx. 7 oz. Instead of sprinkling all the cheese over the top before baking, I sprinkled half over half the spaghetti mixture and the other half over the top of the full amount."
"I loved baked pasta, and this is a great twist on traditional spaghetti. My only negative is that it can be a little dry."
"I made this with the Barilla PLUS Protein Spaghetti which made a very hearty meal. I only had a 24 oz jar of spag sauce so I added a good splash of HOT taco sauce to make up for the difference. LOVED it! I loved mixing the bake with the lettuce, sour cream and tomatoes- very good. You may want to try a milder sauce though if you don't like things too spicy. Even my kids liked it!"
